CO2 repositories
Carbon capture is the process of capturing waste carbon dioxide (CO 2) from large point
sources, such as fossil fuel power plants, transporting it to a storage site, and depositing
it where it will not enter the atmosphere, normally an underground geological
formation. The aim is to prevent the release of large quantities of CO 2 into the
Carbon capture and storage is a good solution to climate change because it can reduce
emissions by 8090%. Hydrocarbon traps provide a location to permanently store
Carbon dioxide in the rocks, anticline traps and salt dome traps are most useful for
storing CO2 as they have the largest repositories.
However, it uses a lot of energy to pump the gas into the ground; around 1040% of the
energy produced by the power station must be used to permanently store the
hydrocarbons. If there was to be a wide adoption of CCS it may reduce the carbon
emissions drastically, but because it uses so much power, it is unlikely that there would
ever be complete conversion to Carbon capture.
The CO 2 from factories is captured, turned into a liquid and transported through
pipelines or by boat to a hydrocarbon trap where it can be stored permanently.
However, CO2 repositories have no effect on fuel emissions from cars, trains, planes or
any transport vehicle; while also not having any effect on the extraction of fuel. It is an
expensive solution to the problem but works relatively well. The major problem is the
potential for a spill or the pipeline breaks, because we haven't be doing it long, there are
bound to be mistakes in the early years, which would only compromise CCS as a climate
change mitigation option.
Pro Con
Reduced emissions from fuel stations by Can only be used at fuel stations
Hydrocarbon traps are already in place Expensive
Permanent solution Reduced energy efficiency by 1040%
Could help combat climate change Only anticline traps and salt dome traps
provide enough space for a reservoir
Has potential to capture half the world's Unlikely ever to be used worldwide
CO2 emissions
Not having to create any storage Has no effect on fuel emissions from travel
